The LFP asked football's world governing body for clarification on the status of the Under-21 Professional Development League, where three over-aged outfield players are allowed, before making an announcement.

Fifa told the LFP that the under-21 league games had to be considered as official.

"In application of the decision, the LFP has no other choice but to ban Hatem Ben Arfa from playing official matches with Nice until the end of the season," a statement said.

Fifa regulations state that "players may be registered with a maximum of three clubs during one season. During this period, the player is only eligible to play official matches for two clubs".
